Secured in the Floor for Mercy's Wrath

Mistress Mercy stands barefoot on the black floor box that locks her slave in place, his head framed in the hole, arms pinned at the sides, naked body stretched across the patterned rug. She brings the thin cane down across the soles of his feet, then his thighs, then the backs of his hands, each strike landing sharp and precise. She steps over his face so he can press his mouth to her tattooed feet, then draws her foot back and drives a kick straight into his balls. He jerks in the stocks as she works him over, caning and kicking in a steady rhythm while he stays locked and available.

She gathers the string of black clothespins and clips them one after another along his balls and the skin around his cock until they form a tight zipper. She looks down at him through the hole, then yanks the string so the pins rip free in one pull. She tells him to get used to having his balls worked over. The slave breaks, crying like a baby while she stands over him and claims every twitch.
